Which risk sharply increased within early Ming Dynasty construction when gunpowder's explosive capability was adapted to quickly dismantle obstacles?

💡 Explanation

Soil liquefaction risk escalates because explosives induce rapid ground displacement, exceeding the soil's shear strength and supporting hydrostatic skeletons. Therefore, foundations become unstable, rather than inducing resonance or sympathetic detonation which were not primary concerns given gunpowder's crude composition.
